Here I have split the geographic regions of Kentucky into 6 standard geological zones. The state could be more precisely split up into several more geological areas, but as for now it is only into these 6. As more waterfalls are added, discovered and shared with this website, the zones may be split into more geological areas to more specifically classify the waterfalls.
The six zones are listed on the right, top menu, and the waterfalls that exist in those zones are found there in alphabetical order.
Check out the full size version of the map as well to see it much, much better.
